This is just a warning to alert you that these are 2 different methods that
have the same name "- init:" but not the same parameter definition.  
C++ would have treated this as 2 really different member functions that
cannot override each other.  In Objective-C, you many have situations 
where you wouldn't know what is the exact kind of object that you're 
dealing with and then you wouldn't be sure what kind of parameter the
method -init: (which is may be implemented in many of your classes)
should take.
For example: you have an OrdCltn called "ordCltn" where you mix objects 
of classes RP and RS and you want to init: all it's members.
Since init: receives different parameter in RP and RS, you would
not be able to use the line:
[ordCltn elementsPerform: @selector(init:) with: yourValue];

Anyway, it's only a warnning.
